In this science fair project, use an infrared thermometer to measure the temperature of differently colored paper exposed to sunlight, and calculate energy emission using the Stefan-Boltzmann equation. Find discussion questions, a list...

The goal of this plant biology science fair project is to make and test an herbicide made from the leaves of the black walnut tree and investigate the toxicity of black walnut trees.

The goal of this science fair project is to build batch solar collectors from different colors of plastic bags and see which collector is the most efficient in heating water.

The objective of this electricity and electronics science fair project is to build a dance pad that flashes lights when you step on it.

Biotechnology science fair project to investigate the bioluminescence of dinoflagellates.

In this energy science fair project, the student will use ocean buoy data to determine if any locations along the coasts of the United States are appropriate for building wave energy power systems.

In this science fair project, investigate the chemical kinetics of the famous iodine clock reaction. This classic experiment requires about a week to complete.

In this biology science fair project, test various amounts of glucose to see which ones attract and which repel (chemotaxis) growing Physarum polycephalum slime mold.

Here's a good way to get yourself on TV. This science fair project will help you learn how to predict the weather. So who knows, maybe you'll be more accurate than your local meteorologist.

The great majority of people have a distinct hand preference. The goal of this science fair project is to determine whether non-primate mammals (e.g., dogs or cats) have a paw preference, which might indicate lateralization of function...

In this science fair project you'll discover how to turn the ocean into a source of freshwater by using the power of the Sun, and the water cycle. You will ultimately find just how salinity affects this process.

So you've just heard the "Happy Birthday" song and now it's time to blow out the candles. If you are sitting far away from the candles, you know you'll have to blow harder to get them all out than if you were sitting closer. In this...

Taking advantage of free energy can reduce our dependence on fossil fuels, which are harmful to our environment. In this science fair project, you will work with a solar panel, which is a collector of free energy, and investigate how...

Humans need food, water, and warm shelter to survive. But a lot of humans depend on fossil fuels to supply gas and electricity to heat our homes. But burning fossil fuels to create energy is harmful to the environment. In this science...

In this science fair project, you will investigate the different uses of electricity in your home. By identifying appliances, and determining how much energy they use, as well as which are phantom loaders, you can determine if there are...

Water creates a lot of energy, just look at the Grand Canyon. In this science fair project, you will demonstrate the power of water by converting the kinetic energy in moving water to mechanical energy, which will lift a small weight.

Lots of people enjoy roller coasters, but not many understand why they feel the strange excitement they do when riding them. In this science fair project, you will build and use an accelerometer to figure out and measure gravity-induced...

Check out this science fair project to determine how much power your PC really uses, and if it is an energy hog, how you can reduce its appetite for energy. You will learn how to profile and streamline your computer's power usage, while...

In this science fair project, you will learn more about wind-powered devices, like pinwheels. Much like pinwheels, we react in different ways to the direction of the wind when we ride bikes, or even try to walk.

Around 50 million years ago, the mammalian ancestor of today's whales returned to the ocean. In this genomics science fair project, you will use mitochondrial protein sequencing to trace the evolution of whales and identify their closest...

How do you like your mashed potatoes? Thin and whipped smooth? Or thick and mashed into chunks? Your mouth checks out not just the taste of your food, but its viscosity, or how it flows on your tongue, every time you take a bite. In this...

Do you like to watch hummingbirds? Have you ever wondered why there is specialty hummingbird food? What is it about the food that makes it so appealing? In this zoology science fair project, you will observe these remarkable creatures...

A cricket as a thermometer? Yes, that's right. In this science fair project, you'll investigate how the chirps of these tiny creatures can do more than lull you to sleep-they can tell you the temperature.

Have you ever pulled a muscle or just been sore after a long day of work or exercise? Hot showers are great, but maybe you've used the more convenient heat packs. Heat packs, which you can buy at grocery or drug stores to soothe aching...
